i like the tango a lot but i have no idea which ball will last longer but i once had a ball with a weather coating on it so u can use it in snow, rain, etc. and it was glossier and shinier but that made it more durable against the wall.

All T90 balls are worth the buy. If you're looking for an even cheaper ball, go to an outlet mall with a Nike store and buy some T90 Radiant balls (from the previous T90 line). The T90 spectra, the T90 Strike, anything are quite good. Just be aware that they scratch rather easily on pavement, but if you're afraid of that, Adidas Finale (i think 20$) is nice and durable.
